Hey guys, you are my last hope. I have looked up everywhere how to make a server with mods AND plugins but I always get one or the other. I'm trying to make a Pixelmon server with the use of plugins for Mac. I can do a regular server and get the mods with no plugins, or I get a bukkit server with plugins and no mods. Keep in mind that this is for Mac. If anyone could help me out that would be greatly appreciated. Thanks
